Production has been under way on Marvel's second Phase Three movie Doctor Strange since November, and we've already seen a few photos from the set featuring star Benedict Cumberbatch in costume. Today we have another image from the shoot, courtesy of executive producer Louis D'Esposito, who is pictured alongside director Scott Derrickson and producer Stephen Broussard on the set. A closer look at this image reveals a door in the background that features the Seal of the Vishanti, which could indicate that Doctor Strange will feature the Sorcerer Supreme's Sanctum Sanctorum.

The image also features an artifact in front of the door, which could be the Eye of Agamotto. In the Marvel Comics, the Doctor uses this device to defeat Dormammu. The Sanctum Santorum is a building that was built upon the site of pagan sacrifices, and before that Native American rituals, which is said to be a focal point for supernatural energies. While we don't have confirmation if this room actually is the Sanctum Santorum, it could also mean that this set is the home of The Ancient One (Tilda Swinton).

This adaptation is based on the character created by Stan Lee and artist Steve Ditko. After a severe accident that leaves both his hands injured and unable to perform surgery, Doctor Strange goes on a trek to find help. He soon encounters the Ancient One. His career thought to be destroyed, the brilliant but arrogant surgeon gets a new lease on life when this sorcerer takes him under his wing. The Ancient One trains him to defend the world against evil as he becomes the Sorcerer Supreme.
